ETL Testing in Less Time, With Greater Coverage, to Deliver Trusted Data

Much ETL testing today is done by SQL scripting or “eyeballing” of data on spreadsheets. These approaches to ETL testing are very time-consuming, error-prone, and seldom provide complete test coverage. ETL testing tool can accelerate and automate ETL testing in both production environments and development & test. This means that you can deliver complete, repeatable and auditable test coverage in less time with no programming skills required.

ETL Testing Use Cases
» Production Validation Testing: (testing the data before moving into production). Sometimes called “table balancing” or “production reconciliation,” this type of ETL testing is done on data as it is being moved into production systems. The data in your production systems has to be right in order to support your business decision making. ETL testing automation and management capabilities ensure that your production systems are not compromised by the data update process.

» Source to Target Testing: (data is transformed). This type of ETL testing validates that the data values after a transformation are the expected data values. The ETL tool has a large set of pre-built operators with no programming skills required.

» Application Upgrades: This type of ETL testing validates that the data coming from an older application or repository is exactly the same as the data in the new application or repository. Most of this type of ETL testing can be automatically generated, saving substantial test development time.

Benefits of ETL Testing
  • Flexible testing process – Accurate, consistent, and reliable
  • Independently validate information upstream, downstream, and within ETL
  • Automatically detect errors and prevent them from propagating
  • Minimize the risk of the data loss
  • Data security
  • Data Accuracy
  • Reporting efficiency
